Opening skylights for homes and businesses in Angus & Dundee

Warm, moist air rises and collects in a roof lantern, so condensation can form on cold winter mornings, especially over kitchens and bathrooms. Thermally broken frames, warm-edge spacers and good room ventilation reduce it, and opening vents in the lantern can release warm air in summer.

Cutting a new opening for a roof lantern or skylight usually means trimming joists or rafters, so the roof can carry the load around the hole. Building regulations approval is generally needed for a new rooflight, covering structure, energy performance and, near a boundary, fire performance.

Roof lanterns are made in rectangular, square and octagonal shapes, with hipped or gable ends. Frames are usually powder-coated aluminium, often grey or black outside and white inside. Manufacturing lead times depend on size and colour, and the expected timescale is confirmed in writing with the quote.

The price of a roof lantern or skylight depends on the size and shape, glass specification, frame colour, opening vents or electric operation, and whether the upstand already exists or needs building. Access to the roof and lifting large units add labour. See the guide prices for typical ranges.

What applies in Angus & Dundee

Section 4 (Safety) of the Scottish Technical Handbooks covers glazing that people could collide with, such as glass in and beside doors and low-level glazing, where safety glass is needed.

Glass in a fire-resisting door or screen must be replaced with fire-rated glazing tested as part of that system. Ordinary toughened glass is not a substitute.

Angus & Dundee has its own coastline, so for homes and businesses near the sea, salt air and wind-driven rain are part of the brief. Coastal lanterns face salt deposits on the glass and frames and strong uplift from wind on exposed roofs. Marine-grade coatings, stainless fixings and secure fixing to a well-built upstand matter, and salt film may need rinsing more often than self-cleaning glass manages alone.

Rural roofs collect more leaves, moss and bird debris, so lanterns need clear upstand drainage and regular checks. Exposed sites see higher wind loads and driving rain, and older outbuildings may need the roof structure strengthening before a lantern is added.

Choosing your roof lanterns

Frame colours

Powder-coated aluminium in grey, black, white or other RAL colours, often dual colour to suit the roof and the room.

Solar-control glass

Neutral or blue-tinted coatings that reduce heat build-up under south or west-facing lanterns while keeping daylight levels high.

Rectangular hipped lantern

A long ridge with hipped ends, suiting most rectangular extensions and kitchens, sized to the opening and the room below.

Square or octagonal lantern

A pyramid or eight-sided design that suits square rooms, orangeries and spaces where a central focal point is wanted.

Roof Lanterns in Angus & Dundee: questions

Why does my roof lantern get condensation?

Condensation forms when warm, moist air from cooking, bathing or drying clothes meets the colder glass and frames at high level. Older single glazed or non thermally broken lanterns suffer most. Thermally broken frames, warm-edge spacers, extractor fans and opening vents reduce it. Some condensation on very cold mornings is normal and clears as the room warms.

Does fitting a roof lantern need building regulations approval?

A new roof lantern or skylight generally needs building regulations approval, because the roof structure is cut and must be supported, and the unit must meet energy standards. Fire performance also matters near a boundary. Replacing a lantern on an existing sound upstand is simpler, and we explain which route applies at survey.

How long does it take to fit a roof lantern?

Fitting a roof lantern on a prepared upstand usually takes a day or less for a typical size, longer for large or complex shapes. The lantern is made to order first, and the lead time depends on its size, shape and colour. Building or rebuilding an upstand is separate roofing work that comes before fitting.

Can I replace my old polycarbonate roof lantern with glass?

Yes, in most cases. A glass lantern is heavier than polycarbonate, so the upstand and roof structure must be able to carry it. If the upstand is sound, level and the right size, a new aluminium lantern can usually sit on it. If not, the upstand is rebuilt first, which the survey will identify.
